While using the digital inputs (bnc or rca to the Transporter's DAC) and connected wirelessly to a SlimServer (6.5.0 or 6.5.1), a drop in wireless connectivity interrupts the audio.  The Transporter will stop and restart with the connectivity issue.  Now, if I completely deny wireless access to the Transporter (by MAC filtering or otherwise) and then turn the Transporter on (using the firmware), the audio hiccup problem disappears.

I suggest altering either the firmware or SlimServer so that a drop in network connectivity does not interrupt the audio from the hard-wired digital audio sources.
